电子服务通常是点对点交付的。然而，电子服务环境为提供增值的综合服务创造了机会，这些服务是通过组合现有的电子服务来提供的。为了使组织能够追求这个商业机会，我们已经开发了deflow，这是一个支持组合服务的规范、制定和管理的系统，建模为由服务流程引擎制定的流程。就服务和服务提供者而言，复合电子服务必须应对高度动态的业务环境。此外，日益激烈的竞争迫使公司提供定制服务，以更好地满足每一位客户的需求。理想情况下，服务流程应该能够透明地适应环境的变化和不同客户的需求，而最少或没有用户干预。此外，应该能够以简单有效的方式动态修改服务流程定义，以管理确实需要用户干预的情况。在本文中，我们将展示flow如何实现这些目标。
E-Services are typically delivered point-to-point. However, the e-service environment creates the opportunity for providingvalue-added, integrated services, which are delivered by composing existing e-services. In order to enable organizations to pursue this business opportunity we have developedeFlow, a system that supports the specification, enactment, and management ofcompositee-services, modeled as processes that are enacted by a service process engine. Composite e-services have to cope with a highly dynamic business environment in terms of services and service providers. In addition, the increased competition forces companies to provide customized services to better satisfy the needs of every individual customer. Ideally, service processes should be able to transparently adapt to changes in the environment and to the needs of different customers with minimal or no user intervention. In addition, it should be possible to dynamically modify service process definitions in a simple and effective way to manage cases where user intervention is indeed required. In this paper we show howeFlowachieves these goals.
